Overview

CVE-2024-45011 is a medium-severity vulnerability. It was published on September 11, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

char: xillybus: Check USB endpoints when probing device

Ensure, as the driver probes the device, that all endpoints that the

driver may attempt to access exist and are of the correct type.

All XillyUSB devices must have a Bulk IN and Bulk OUT endpoint at

address 1. This is verified in xillyusb_setup_base_eps().

On top of that, a XillyUSB device may have additional Bulk OUT

endpoints. The information about these endpoints' addresses is deduced

from a data structure (the IDT) that the driver fetches from the device

while probing it. These endpoints are checked in setup_channels().

A XillyUSB device never has more than one IN endpoint, as all data

towards the host is multiplexed in this single Bulk IN endpoint. This is

why setup_channels() only checks OUT endpoints.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2024-45011?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2024-45011 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
